Chemical Structure

Tetrarhodium dodecacarbonyl CAS 19584-30-6 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Tetrarhodium dodecacarbonyl (CAS 19584-30-6), molecular formula Rh4CO and molecular weight 439.65 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, Tetrarhodium dodecacarbonyl is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
